Why: - Some boards have multiple I2C interfaces - Control when TwoWire.begin() is called This change addresses the need by: - Option to not begin() Wire - Always be in configured state (no null ptr crash) - Internally use TwoWire pointer - Add example of new functionality - Add possible I2C addresses - Update I2C address in example to be within 0 - 127 range
